WATER-MOTOR.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed January 9, 1919. Serial No. 270,283.

To all whom it may concern:

Be it known that l, Orr-ii L. flows, of Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in ater-Motors; and 1 do hereby declare the following to bea full, clear, and exact description of the in vention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The object of my invention is to provide an improved type of watermotor, comprising a frame suspended on a track above the stream of waterand on which frame is a supporting beam for the cradle of the vanecarrier, the support and the cradle being capable of being raised so asto lift the vane carrier from the current, the carrier being so arrangedon the cradle that it may be swung horizontally in the event of unduepressure created either by heavy currents or by the normal current andflotsam.

. In the accompanying drawings, Figure 1 is a view in side elevation.Fig. 2 is a view at right angles to Fig. 1, parts being in section. Fig.3 i a top plan view and Figs. at and 5 illustrate a slight modificationof the means for suspending the frame.

In the drawings, 1 designates a vertically disposed frame which issuspended on elevated ways 2 appropriately positioned between uprightsarranged on opposite banks of astream. A swinging beam 4 is carried bythe frame 1 and may be secured thereto at any one of several elevationsby a cross rod 5 which serves as a pivot for the beam. The latter is ofrectangular form and is provided with a centrally and longitudinallydisposed track 6 over which travels a suspended balancing weight Theposition of this weight on the beam is controlled by guiding ropes 8 and9 which travel, re spectively, over pulleys 10 and 11, the ropes beingconnected with the weight and after passing around these pulleys theyare carried up over appropriately journaled heaves on the frame 1 anduprights 3, and then to any convenient point adjacent one of thesupporting uprights 3 where theymay be controlled for moving the weight7 along its track. It will be apparent, see Fig. 2, that a pull on rope9, with the rope 8 loose, will draw weight 7 to the upwardly extendingend of the beam 4.

A vertically disposed rectangular frame 20, with its uprights indicatedat 21, forms a cradle for a vane carrier to be later decribed. Theconnection between the cradle and the beam is such as to insure ananprorh mately vertical movement of the cradle in the up and downmovements of the beam. The arms 21 are provided with a series of spacedapart apertures permitting adjust ment of the cradle on the beam variousheights. Extending centrally of the cradle and supported thereby is arod 2% which forms a pivot for a horizontally disposed bar 25c0nst1tuting a vane carrier, this bar being suitably braced by cables26, guyed to the cradle. A platform 22 is a partof the vane carrier andis connected with an held in spaced relation to the part 25 by uprights26" so as to insure a turning of the platform in the turning movement ofthe vane carrier, the platform forming a support for a pump 23.Preferably the vane carrier ar ranged so that a greater portion of itsleugt is at one side of the pivot, see Figs. 1 an? 2,. 27 deslgnates aseries of vanes journaed on the vane carrier and appropriately geared toconvey power to the pump the l t having suitable land connections. Inore that the vane carrler may be maintained in position against thecurrent I provide a weight 28 which is suspended from a cable 29 passingover a sheave on the frame 1, the other end of the cable being connectedwith the vane carrier. The power of this weight is just sufficient tomaintain the vane carrier in position across the streams for the normalcurrent of the latter and if excessive currents appear the carrier willswing about its vertical pivot on the cradle. The gathering of flotsamabout the vanes or the carrier which would create extraordinary pressureis suflicient to overcome the power of the weight and move the carrierso that the vanes will be ineffective. To prevent swinging of the cradleabout its pivotal connection with the beam chains 30 are connected tothe arms 21 and the vertically disposed frame 1. This chain also aids inmaintaining the desired angularity between the cradle and beam as wellas between the beam and the frame.

The use of my improved motor will be apparent. It is readily suspended,and the depth of the vanes in the current regulated either by elevationof the supporting beam by changing its point of connection with theframe, or by tilting the beam so as to slightly raise the cradle, thelatter being effected by a movement of the balancing weight 7. When itis desired to remove the cradle from the stream, manipulation of therope 9 will efiect movement of the weight 7 along the track 6 to the endof the beam opposite that which carries the cradle. This lessens theWeight on the cradle end of the beam and enables the beam to be morereadily turned about its pivot by pulling on a rope31,'power beingapplied by any preferred means, not shown. Before the parts areelevated, asdescribed, it is advisable to turn the vane carrier aboutits pivot. This is readily effected in any preferred manner.

In Fig. 4 I have shown a derrick from which the frame 1 is suspendedwhere it is impracticable to have a way stretched from one bank of astream to the other. 35 designates a mast or post from which a swingingboom 36 is appropriately suspended, the frame 1 supporting the cradleand vane carrier, both of a like construction to the same parts shown inFigs. 1, 2 and 3, being secured to the boom. For the purpose ofcontrolling the position of the vane carrier in the stream, a weight 37is provided, the cable 38 to which the weight is attached passing over asheave 39 on the post-35 and thence to the cradle at the vane carryingend thereof. The boom 36 is held in position as against swingingmovement by .a cable 40 secured thereto and passing about a sheave 41 ona short post 42, the weight 43 being suspended from the post 35. Formaintaining the vane carrier in operating position I provide acable 414Cand a weight 45, shown in Fig. 5.

I claim as my invention:

1. In a water motor, a frame, a support from which said frame issuspended, a beam pivoted on said frame, a cradle carried by said beam,a vane carrier on said cradle, and means for raising and lowering saidcradle.

2.
